In recent years, female sexuality has been considered an important component of woman’s health, that it may be related to various factors. The aim of this study was test a model of awareness the moment as a mediator of the relationship between sexual anxiety and genital self-image to sexual function. We collected data from 300 heterosexual women that completed the Female Sexual Function Index (FSFI), the Five Fact Mindfulness Questionnaire (FFMQ), the Multidimensional Sexual Self- Concept Questionnaire (MSSCQ), and the Female Genital Self- Image scale (FGSI). Structural equation modeling was used. The findings showed that there was a significant relationship between the genital self- image and the sexual function, and between the sexual anxiety and sexual function. Also, the genital self- image and sexual anxiety had relationship with the awareness the moment separately. Structural equation model revealed a significant relationship between the genital self- image with sexual function through the awareness the moment; and between the sexual anxiety and sexual function through the awareness the moment. Therefore, the better sexual function can occur by more positive genital self- image. Also, we found awareness the moment can mediate the relationship between sexual anxiety and sexual function.
